# Add multiple read replica endpoints to a Gremlin Java connection pool
<a name="best-practices-gremlin-java-multiple"></a>

When creating a Gremlin Java `Cluster` object, you can use the `.addContactPoint()` method to add multiple read replica instances to the connection pool's contact points.

```
Cluster.Builder readerBuilder = Cluster.build()
          .port(8182)
          .minConnectionPoolSize(…)
          .maxConnectionPoolSize(…)
          ………
          .addContactPoint("reader-endpoint-1")
          .addContactPoint("reader-endpoint-2")
```
